Modelling and Comparing Shading Effects of 3D Tree Structures with Virtual Leaves
shadow model TLS LiDAR agroforestry QSM Prunus avium insolation shade cast
2023/12/6
Reduced solar radiation brought about by trees on agricultural land can both positively and negatively affect crop growth. For a better understanding of this issue, we aim for an improved simulation o...
Combining Different Transformations of Ground Hyperspectral Data with Unmanned Aerial Vehicle (UAV) Images for Anthocyanin Estimation in Tree Peony Leaves
hyperspectral tree peony anthocyanin (Anth) unmanned aerial vehicle (UAV)
2023/11/30
To explore rapid anthocyanin (Anth) detection technology based on remote sensing (RS) in tree peony leaves, we considered 30 species of tree peonies located in Shaanxi Province, China. We used an SVC ...
Leaves as bottlenecks: The contribution of tree leaves to hydraulic resistance within the soil?plant?atmosphere continuum
